The mistakes behind most wrong answers
A wrong answer in rounding to tens and hundreds is rarely random. These are the ones that come up most often, each on a real problem — worth knowing before you mark a sheet, because the fix for each is different.
Round 51 to the nearest ten.
51The answer is 50. A child who answers 60 probably counted one group too many or too few.
Round 187 to the nearest ten.
187The answer is 190. A child who answers 200 probably rounded to the wrong place.
Round 198 to the nearest ten.
198The answer is 200. A child who answers 190 probably chopped the digits instead of rounding.
